The victim fell about 20 feet and landed on a small rooftop on the west side of the stadium near Lake Shore Drive, fire spokesman Joe Roccasalva said.

Haverty was taken in critical condition to the hospital, where he was later pronounced dead, officials said. An autopsy is scheduled for Monday.

The fire department needed an aerial tower with a basket to get him down, Roccasalva said.

Witnesses told emergency personnel that they saw the man run up to the ledge and jump.

The incident is the second fatal fall in a week at a major sports arena. On Nov. 21 in Los Angeles, a 2-year-old died after plunging 50 feet from a Staples Center luxury suite.

The boy, Lucas Anthony Tang, had been crawling around the suite during the Lakers game against the Golden State Warriors, sources said. At some point, his parents noticed he was missing and began to look for him.

They did not know then that their son, who would have turned 3 in January, had fallen.
